Connector cables are supplied with the Jarvik 2000 FlowMakerŽ to link the components together: the battery to the controller, the controller to the pump. The cables are color-coded and keyed to ensure that they cannot be connected the wrong way. A latch mechanism allows the cables to "click" together securely, making connections hold up against sudden tugs or strain. A retractable extension cord for connecting the controller and the pump allows the external equipment to be kept at a distance while sleeping or bathing. A "Y" cable is also provided to allow the patient to seamlessly change batteries without stopping the pump.
A patient manual gives detailed guidelines on how to use the external components of the Jarvik 2000 FlowMakerŽ to ensure maximum safety. Patients also carry an identification card with important contact and technical information, which may be necessary in emergency situations.
